My frame re-design using Tenacious SLA resin parts and 3mm carbon fiber tubes worked out really nice, but I'm not sure it's more rigid than a simple PETG print would have been.
This is only the upper portion of the frame (though it does include an integrated battery holder) and weighs in at 14.3g. Still, was a nice learning experience for me...

I'm trying to figure out where I can put it since there's so little room to work with on this frame. The GPS has a compass as well, which further restricts the placement options. Maybe one of the rear arms if I shield the motor wires with some foil? Or on top of the camera?

nice frame! i like carbon tube frames :-)

center of gravity why is all placed in front?

Good Question. I was also wondering how all the electronics will fit on that frame.

Very clever!

I think it's front heavy because it's trying to preserve a deadcat configuration. I say just make it easy and do true-x. I'm also curious what a super bare-bones spartan version with just a single AIO with onboard VTX and a Crossfire could do as far as endurance for long range. I guess you'd need the bec for the Crossfire.

Hey JoyMonkey,

Where do you get the carbon fiber tubes?

That is a really cool    looking frame. Look forward to seeing the completed quad. 

any rcplane hobbyshop should have them, i have some from a local shop, there are all sizes and forms.

i want to try the flywoo motors, hopefully stuff comes back into stock sometime ever.

.......

the GPS disconnected and was flung off in a random direction. I searched for 20 mins, but eventually gave up hope of finding the 1" x 1" GPS in the grass

A few important lessons learned here: always get a few mistakes high before trying anything new and be ready to recover, make sure everything is securely fastened to the quad, and bring backups for everything. 

While I'm waiting for a new GPS, I'm considering swapping in an OpenLager on that UART to do some tuning. I might just flash back to Betaflight now that I know iNav (kinda) works, and get some more flight time on it.

Any ideas for a secure but lightweight mount for a M8Q-5883 GPS?

I lost a BN-180 once literally 10 meters infront of me in short grass after a crash because i double tapped it on the battery strap for a quick test flight.

Everyone thought I was mad walking in circles on a hot sunny day.

This is my cheap, yet very effective, GPS mount;   Pic 1 top view , Pic2 bottom view   Guess what, that plastic won't break. 

1) Cut a piece of plastic.
2) Use clear shrink tubing to secure GPS to plastic.
3) Bolt the plastic assembly to the frame.

I keep plastic from anything with a flat surface: alcohol bottles, MCT Oil bottles {used here}, Peroxide bottles, laundry soap bottles, milk bottles, any plastic. Realize that most of the liquids that we use {at least in the USA} come in some type of plastic container {generally there is a flat surface somewhere}. I cut out the flat portions of all of these containers and keep them. Some of the plastic is heavier than others, some is more pliable, some is clear, some is frosted, some opaque, some has color. In addition to this heavier plastic, I also keep the thin plastic that things are packaged in {blister pack}; you know, that plastic you have to cut with scissors or a knife to get your product out. Thing is, all of this plastic is FREE {or rather included in the cost of some product that you just bought}. We buy a product and this is a by product or side benefit. I call this Recycling.

Oh yeah, most of this plastic can be molded if you are careful with the heat.

Over 2 years ago, I discovered that this thin plastic was great for fabricating small braces and mounts for my tiny whoops.

Right. I'm very much a noob, and wanted to stick to Dave C's frame layout as much as possible. So my frame has all the mounting holes and motors in the exact same position as Dave's #NanoLongRange deadcat frame. For now

These carbon fiber tubes came from McMaster Carr. They're 3mm OD, 2mm ID : https://www.mcmaster.com/2153T115
These tubes can come in handy for all kinds of things, and aren't very expensive, so I picked a bunch up with a hardware order a while back.

Thanks for the compliments. I should probably start my own thread for this build, so I don't clog up V-22's build thread.

Yes, definitely start a BUILD thread. It helps to keep builds separate so we can find them.    

Hey V-22, are you powering your camera from the step-up regulator, or the 5V pad on the FC? Seems like it would be simplest to wire it to the FC's pad, but I'm not sure how stable that 5V rail stays when voltage gets low.

JoyMonkey that frame looks sick

Yes, step-up regulator directly connected to the battery. The 5V pads on the FC cannot supply the necessary current to power the VTX as the Li-ion voltage drops.
